Verdict
The clearest difference is review sentiment: V.DialogueF1 at 100% against Fuel's 50%. V.DialogueF1 also leads on rating (5.0 vs 3.1) and update cadence (monthly vs every 10 months). Fuel's advantage is ratings volume (33 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
